Abstract

The first order spring (291) hand lever (20) is used to lock the spanner and is connected externally to the primary arm (3) by a pinned (42,44) fulcrum strap (43). A cranked branch (46) traverses an arm eyelet (47). Pivoting of the upper lever (20) moves the slide onto an indented bar (18) which cantilevers normally from the lower arm (4). The lever is pulled towards the arm to effect jaw (1,2) convergance. The spring delays pivoting until a nut is gripped. The movement of branch through the eyelet causes the lever to displace axially as it pivots, thus, pushing the slide onto the rack and locking the jaws on the nut.
